13,14 is equivalent to 2 times of sidewall thickness, and separation trough 13 is halved minor face, and 2 separation troughs 14 will be grown the limit trisection.Like this, the interval of separation trough is necessarily promptly identical.

When assembling folding carton, two lateral process 21a, the 31a of connecting pin 21,31 each long and

short sidewall

20,30, that give prominence to towards long and

short sidewall

20,30 bottoms, push from the shape through hole 12a of lower panel 10, the downward enlarged of 11a, two lateral process 31a, 21a etc. are stuck in shape through hole 12a, the 11a.

The following describes running condition of the present utility model.

Two lateral process 21a, 31a towards the outstanding connecting pin 21,31 in the bottom of long and

short sidewall

20,30 push from the shape through hole 12a of lower panel 10, the downward enlarged of 11a, make two lateral processes be stuck in shape through hole and assemble interiorly.Like this, and adopt hinge similarly, long and short sidewall can be connected on the high jag and low jag above the long and short limit of lower panel 10.

Because short sidewall is connected on the low jag 11 that is equivalent to sidewall thickness, so, when folding, earlier short sidewall 30 is folded on lower panel 10 top.Like this, the sidewall thickness of short sidewall 30 and the height of low jag are located on a level.Then folding long sidewall 20 is owing to long sidewall overlaps on the short sidewall, so with the high jag on a level that is equivalent to 2 times of sidewall thickness, like this, the tote box volume when folding can minimum (seeing Fig. 2, Fig. 3).

In addition, be located at the exposed portions serve that fender 22 on the inboard right angle orientation in long sidewall two ends covers folding earlier short sidewall, firmly with its protection.

Folding carton to be launched, when using, earlier two long sidewalls 20 outwards be launched as case.Because two lateral process 21a of connecting pin 21 are stuck in the shape through hole 12a, so, long sidewall 20 deployable one-tenth vertical configurations.Then, by shape through hole 11a, two short sidewalls 30 are vertically launched, and, the two inboard grip parts 41 of pulling out operating bar 40 (this pulls out the both sides that operating bar 40 is located at two short sidewall lateral surface tops symmetrically) are hung over two to be referred to inwardly draw, by elastic force, from the through hole 33a of central tabula end 33 outside＞shape flexure strip 42 moves towards through hole 33a is inner, simultaneously, front end through hole 32 outside outstanding outside copulational protuberances 43 towards short sidewall 30 both sides bury in front end through hole 32, and two short sidewalls 30 are launched fully.

At this moment; unclamp two fingers that grip part, both sides 41 is inwardly drawn; outside copulational protuberance 43 enters and engages when blocking in the through hole 23; two short sidewalls 30 are supported by the fender of two long sidewalls, 20 both sides; copulational protuberance 43 is stuck in and engages in the through hole 23; like this, two short sidewalls 30 and two long sidewalls 20 keep crash-resistant square.

When article are packed into case, lower end 52 is fixed in a pair of vertical through hole 53, this a pair of vertical through hole is located in a sidepiece of two short sidewall pars intermedias and two long sidewalls, supporting slice 50 pushes the inboard by elastic force with a top part, to the outside projection 51 on supporting slice 50 its tops of pull-up of this state, expand open and sidewall between the interval, go into putting down in writing the card of Item Title, specification etc. at spatial interpolation, a pair of card rest pin is held card under the arm with elastic force, card can be inserted in advance the side (see figure 7) of case.

According to the utility model, be to form horizontal, vertical separation trough on 3: 2 the bottom surface of lower panel at the ratio of long and short edge lengths, the width of this separation trough is equivalent to 2 times of sidewall thickness, this separation trough is halved minor face, to grow the limit trisection, like this, the interval between separation trough is certain.A plurality of tote boxs when stacked up and down, as Fig. 8, shown in Figure 9, are laterally placed 2 casees,,, the minor face of these 3 vertical casees and the long limit of 2 transverse box are joined 3 case end wises placements at this state, then, stacked case on them again.At this moment, below the end of case embed above in the longitudinal and transverse separation trough of case, link stackedly in length and breadth mutually, like this, even case is higherly stacked up and down, case can not fall down yet, the part of case can lateral alternate yet.

In addition,, push, make two lateral processes be stuck in shape through hole and assemble interiorly from the downward enlarged of the shape through hole of lower panel two lateral processes towards the outstanding connecting pin of long and short lower sidewall.Like this, in the utility model, can with adopt hinge similarly, long and short sidewall is connected on the high jag and low jag above the long and short limit of lower panel.

Since short sidewall be connected with the cooresponding low jag of sidewall thickness on, so, when folding, earlier short sidewall is folded on lower panel top.Like this, lack the height of the sidewall thickness of sidewall and low jag in same level.Then, during folding long sidewall because long sidewall overlaps on the short sidewall, so, with the high jag that is equivalent to 2 times of sidewall thickness in same level, like this, the volume of the tote box after folding can minimize.
